Northern Mariana IslandsIslas Mariånas
First trip: Saipan as the single base for 4–5 nights, with Managaha Island by boat and Tinian or Rota as a day or overnight by small plane or ferry; the northern islands are uninhabited and not for independent visits.
The Commonwealth of the Northern Mariana Islands is a US territory: US immigration rules have applied since 2009, with the same Guam–CNMI Visa Waiver Program for some nationalities. Almost all visitors stay on Saipan; Tinian and Rota are quieter. Typhoons, notably Yutu in 2018, are the main risk, mostly from July to November.

Country rules
- US entry rules apply: a US visa, ESTA, or eligibility for the Guam–CNMI Visa Waiver Program. Check US Customs and Border Protection for your passport, and note that the Guam–CNMI waiver does not allow travel on to the rest of the US.
- The CNMI runs its own customs and quarantine check: declare food, plants and animal products on arrival.
- Second World War sites (Banzai Cliff, Tinian's North Field) are memorials; do not remove relics or climb on structures.
Etiquette
- Håfa adai (Chamorro) and Tirow (Carolinian) are the greetings.
- Respect memorials and latte stone sites.
- Dress modestly away from beaches.
- Typhoon season (mainly Jul–Nov)
- Storms can close airports and cut inter-island flights.
- Asian holiday peaks (Golden Week, Lunar New Year, Chuseok)
- Saipan hotels fill with visitors from Japan, Korea and China.

- Unexploded wartime ordnance is still found in the jungle; stay on paths.
